Brawn (person)

To BRAWN, Earth is essentially a hostile environment -- and he loves it. Strong, rugged, agile -- the most macho of all Autobots. Delights in challenges. Sorry for those not as tough as himself. Second strongest Autobot -- can lift 190,000 pounds and knock down a small building with one punch. High resistance to artillery fire. Vulnerable to attack by electromagnetic waves.

Brawn really got gyped in the cartoon. His specs describe him as the "second strongest Autobot" of the first toy run (after Optimus Prime, of course), meaning the little guy could go toe-to-toe with Megatron and hold his own. In the comic you'd see this, but never in the show. Heck, in Transformers: The Movie he was one of the first to get shot and killed aboard the Autobot shuttle when the Decepticons boarded. Nitpickers to this day maintain that there's no way Brawn could've gone down so easily, and insist that he survived to make cameo appearances in later cartoon episodes.
